Abstract: An image represented as an array of digitally valued picture elements is selectively reduced or expanded in size by addition or subtraction of rows and lines of picture elements at positions which are the closest approximation to the newly scaled base, the picture elements corresponding to grey scale values. Reproducing a given image is scanned by photodetector elements (18). The added lines are duplicative of the next adjacent line. Subsequent lines of picture elements are shifted to close the gaps. A dot generator array (such as ink jet array, cathode ray tube, electrostatic or thermal recording system) responsive to the digital values of the picture elements generates the image in scanning fashion across a copy sheet at a modified scale factor in a single or in successive scans, which may occur at the same location or after transmission of the digitally valued pictured data to a different location.

Abstract: A power switch device comprises an asymmetrically blocking thyristor (ASCR), with which a diode is connected in series. The ASCR as well as the diode require only about one half the central zone thickness as compared with a symmetrically blocking thyristor laid out for the same blocking voltage in reverse direction (URRM). For the series connection of the ASCR and diode, this results in a much lower blocking delay charge (Qrr).

Abstract: Apparatus for mixing liquid and liquid suspension mediums in vessels with a mixing impeller shaft system of a composite of fibrous and plastic material of a structural configuration to enable the use of such material in commercial and industrial applications where the reaction loads of the medium on the system militate against the use of composite fibrous and plastic material. The system utilizes impellers having blades which distribute the reaction load through a hub on a mounting area of a shaft with keys and keyways in a manner to avoid stress risers unamicable to the composite material and which can cause failure thereof. Separate keys and keyways are provided to oppose the thrust due to the reaction loads and to oppose the torque due to such loads. Plural thrust keyways may be used to enable the impeller to be located at different positions on the shaft and at selected heights above the floor of the mixing vessel. Proplets on the tips of the blades extend entirely in the direction of the low pressure surface of the blades to control the flow field in the vessel and provide a more axial velocity profile of the inlet flow to the impeller which is nearly axial and substantially reduces the strength of the tip vortices.

IPC: E21B7/20
Filed: 1989-04-25
Abstract: The present invention relates to a drill string element adapted to be coupled to other similar drill string elements by thread connections (19) thus forming a drill string for top hammer drilling. Each drill string element includes at least one rod (15;15 min ;15 sec ) for transferring impact energy to a drill bit (11) provided at the lower end of the drill string (10) and a tube assembly (21;21 min ;21 sec ) for transferring rotation to the drill bit (11), said tube assembly surrounding the rod. When handling drill string elements of the above-mentioned type it is extremely important that this handling can take place in a safe way without any risk for accidents during operation working site. Previously known drill string elements of the type in question have the disadvantage that the rod can fall out of the tube assembly in one direction. Also the accessibility to the interior of the drill string element in connection with repairs/service must be considered and the drill string elements must stay intact during operation, especially when they are unscrewed from each other. The invention is characterized by that the tube assembly (21;21 min ;21 sec ) in the area of the two ends of the rod (15;15 min ;15 sec ) is provided with an internal diameter reducing (27;27 min ,27 sec ;27'''), and that the rod (15;15 min ;15 sec ) is provided with cooperating radial projections (28;28 min ) or shoulder means (28 sec ). Also the tube assembly (21;21 min ;21 sec ) includes at least two tubular members (18;18 min ;18 sec ) that are coupled to each other by a thread connection that is harder to unscrew than the thread connection (19) for coupling together the drill string elements.

Abstract: A package (18) having a handle (70) for housing granular or similar products. The handle is a substantially flat strap handle which has a barb member (76) on each end. The handle is inserted into two opposing openings (64) in the side wall (34) of the package. A section of the side wall adjacent each of the apertures includes a liner (80) which separates the granular contents of the package from the area immediately surrounding the aperture. The liner is adapted to prevent the flow of granular contents out through the aperture. The package can be formed from a sleeve which, even with the handle inserted, is substantially flat. Also, with the package assembled the handle rests against the side wall of the package allowing shipping virtually as if the package did not have a handle.

Abstract: The present invention comprises a wood bit for use in wood working applications. The blade of the bit is generally spade shaped having cutting spurs on each corner of the blade, a central point projecting from the leading end of the blade, and hooked cutting edges. A progressive transfer die is used to bend the leading end of the blade and forge a continuous hook angle extending along the side cutting spur, the lateral shoulder, and the central point of the blade. The forging of a hook extending from each side of the blade converging at a central point provides a hook along the leading end of the blade projecting outwardly (in the direction of rotation) pass the plane of the blade face. The leading end of the hook is beveled forming a continuous cutting edge extending along the hook from the outer side wall of the blade through the outside cutting spurs, along the lateral shoulders, and along each side of the central point. <IMAGE>

Abstract: A method of providing warning of the onset of the fertile phase of the human ovulation cycle, involving measurement in absolute or relative terms of the body fluid concentration of an analyte such as estradiol or a metabolite thereof wherein if in the current cycle a concentration measurement conducted at about the termination of menses reveals a body fluid concentration that is typical of that found in the body fluid of an average human female subject about 3 days prior to the time of ovulation during a 28-day cycle, the current cycle is immediately declared to be in its fertile phase. Where the analyte is E3G, the E3G concentration measurement is conducted on at least one or numerical days 4 to 7 of the current cycle, counting from the onset of menses, and the fertile phase is declared immediately if the E3G measurement reveals a concentration equal to or greater than a threshold concentration chosen in the range of about 25 to about 35 ng/ml.
